Patented Feb. 17, 1942 STATES FFICE 1 Claim.

This invention relates to a container designed for containing liquidswhich freeze under freezing temperature, the primary object of the invention being to provide a collapsible body held within the container tocompensate for the expansion of the liquid during the freezing thereof,thereby insuring against the container being broken by the expansion ofthe frozen material within the container.

An object of the invention is to provide a device of this characterwhich may be supported in such a manner within the container that thecompressible body may be readily observed, to determine the condition ofthe compressible body.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein described, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

Figure 1 is a vertical sectional View through a container equipped withan expansible body, constructed in accordance with the invention.

Figure 2 is a transverse sectional View taken on line 2-2 of Figure 1.

Figure 3 is a vertical sectional view through a container equipped withan expansible body designed to float within the container.

Referring to the drawing in detail, the container is indicated generallyby the reference character 5, and as shown is provided with an inletpipe G, and an outlet pipe I.

The bottom of the container is formed with an opening, the wall of whichis threaded to accommodate the plug 8, by means of which access to theinterior of the container may be had.

As shown, the opening is formed in such a way as to provide a shoulder 9against which the flange ill of the neck I! is held, by the action ofthe plug 8, which is shown as positioned thereagainst.

The expansible body IQ, of which the neck ll forms a part, is preferablyconstructed of rubber, and filled with air to be compressed by theexpansion of the liquid in the container, freezing.

In the form of the invention as shown by Figure 3 of the drawing, theexpansible member or body i3 is placed within the container, to float tothe top of the container, as shown.

The body It in this form of the invention is also constructed of rubbermaterial and filled with air to be compressed, due to the expansion ofthe liquid freezing within the container.

The reference character l4 designates the cover for the container, whichmay be held in position by any suitable means.

From the foregoing it will be seen that due to the construction shownand described, a space is provided at all times within the container, tocompensate for the expansion of the material freezing. It is obviousthat as the material in the container freezes, pressure will be directedto the expansible body, compressing the air in the body, andcompensating for the expansion, thereby relieving the walls of thecontainer of undue strain which, under ordinary conditions, would breakor rupture the container to cause the same to leak.

What is claimed is:

The combination with a receptacle having an opening in the bottomthereof and having inlet and outlet pipes connected with the receptacleand disposed in a horizontal line drawn through the center of thereceptacle, of a substantially shallow circular hollow body portionconstructed of rubber material, fitted within the receptacle, throughthe opening in the bottom of the receptacle, a neck forming a part ofthe body portion through which air is directed to the body portioninflating the body portion, said neck being fitted within the opening inthe bottom of the receptacle, the upper surface of the hollow bodyportion being spaced an appreciable distance below the direct line offlow of Water through the pipes and receptacle, and means for removablysecuring the neck of the body portion, within the opening in the bottomof the receptacle.
